// DESCRIPTION:
//
//  This file implements the TWin1251Converter class, which handles converting
//  the CP1251 encoding to and from the internal Unicode format. We really
//  just have to provide it the mapping arrays.

        //  achFromMap
        //      This is the 'from' map that maps from the external encoding to the
        //      internal Unicode encoding. External code point X is used to index
        //      the table, and that entry holds the equivalent Unicode value. If
        //      there is no legal external code point at that index, its 0xFFFF.
        //
        //  achToMap
        //      This is the table that maps from the internal Unicode encoding to
        //      the external encoding. The table is sorted by the Unicode value.
        //
        //  c1RepChar
        //      This is the replacement char, which is used to represent Unicode
        //      values that cannot be represented, if converter is set up to do
        //      that.
        //
        //  c4ToMapSize
        //      This is the number of entries in the 'to' map. Since there can be
        //      more than one Unicode value that maps to a particular external
        //      code point, its not just a 256 entry table.
